Here are some user instances reporting about this error:

Instance 2: “I recently issued a new laptop to a user. No changes to how we do that, and no changes on the network that would restrict access to attaching documents from a shared drive.

What If Nothing Works?

Most of the Outlook errors are attributed to problems in PST file. So, if none of the above workaround helps fix the error, repairing the PST file may help.

Use the Outlook built-in Inbox Repair Tool (also referred to as ScanPST.exe) to repair the Outlook data file (.pst). Be wary, though, the built-in repair utility may fail to repair corrupt PST file in the following circumstances:

  • PST file is large or severely damaged (corrupted)
  • Unexpected errors crop up in Outlook that ScanPST.exe cannot fix

Also, you may have to run the ScanPST.exe utility several times to fully repair the Outlook data file. If the utility fails to fix corrupted PST file, choose an alternative to ScanPST.exe. Stellar Repair for Outlook software is the best ScanPST.exe alternative to repair corrupt PST file and recover its data. The software can parse severely corrupted PST file of any size and recovers all mailbox data, including deleted emails in a quick and precise manner.
